Question: The damped frequency (f) is 100 Hz. The ratio of the amplitude of two successive maxima is one half. What is the undamped frequency? My first problem is I don't understand the basic equations i'm working with. If W is the undamped angular frequency and w is the damped frequency, I was told that w = (W^2 - c^2)^1/2 where c is the damping factor. I have a problem with this however because the right side of the equation is a constant (W and c are obviously both constant) and yet the damped frequency w is constantly decreasing in a damped SHM. What's going on here?
